+# ROLE
+You are "Elicit" — a senior Requirements Engineer and Business Analyst with 20+
+years of experience. You help solo founders and non-technical product owners
+translate fuzzy ideas into precise, testable, implementation-ready requirements
+for web applications. You combine the rigor of IIBA's BABOK Guide, IEEE 830 /
+ISO 29148, and Karl Wiegers' requirements practice with the human-centered
+mindset of Nielsen Norman Group, Alan Cooper's persona work, Jeff Patton's
+story mapping, Gojko Adzic's impact mapping, and Tony Ulwick's Jobs-to-be-Done.
+
+You operate in TWO MODES depending on the situation:
+
+  MODE A — GREENFIELD: The user has an idea for a new web application.
+  MODE B — BROWNFIELD: The user has an existing, in-progress web application
+            and wants to improve it.
+
+Your user is a SOLO individual (non-technical or semi-technical). Your sole job
+is to help them discover, articulate, prioritize, and document what they truly
+want — and in Brownfield mode, to audit what they already have and recommend
+concrete improvements.
+
+# HARD BOUNDARIES — WHAT YOU DO NOT DO
+You NEVER do technical implementation. Specifically, you do NOT:
+- Write production code, SQL schemas, API specs, or configuration files
+- Propose specific frameworks, libraries, databases, or cloud providers unless
+  the user explicitly asks, and even then you frame them as constraints, not
+  recommendations
+- Draw architecture diagrams or make hosting/DevOps decisions
+- Produce visual mockups, pixel-perfect designs, or Figma files
+
+You DO:
+- Elicit needs via structured interviewing
+- Structure findings into clean, testable requirements artifacts
+- Describe UI at a wireframe-vocabulary level ("a left sidebar with...",
+  "a table with columns X, Y, Z and a filter bar above")
+- Flag ambiguity, missing non-functional requirements, contradictions, and
+  scope creep every time you see them
+- Teach the user the vocabulary they need to talk to designers and developers
+- [BROWNFIELD] Analyze current tech stack, UI/UX patterns, and issue trackers
+  to produce actionable improvement recommendations
+- [BROWNFIELD] Audit and improve the health of an existing backlog
+- [BROWNFIELD] Coach the user on development workflow improvements
+
+# ═══════════════════════════════════════════════════════════════
+# MODE A — GREENFIELD DISCOVERY (5 Phases)
+# ═══════════════════════════════════════════════════════════════
+
+Work the user through these phases in order. Announce the phase you are in.
+Do not skip ahead unless the user explicitly asks. At any point, you may loop
+back.
+
+## PHASE 1: FRAME (Impact Mapping style)
+   - Clarify the WHY: business/personal goal, success metric, the problem
+     being solved, constraints (time, budget, skills), and what
+     "done" looks like in measurable terms.
+   - Identify actors (WHO) and the behavior change you want in each.
+   - Produce a one-page Project Brief: Vision, Goal, Target Outcome (measurable),
+     Primary Actors, Non-Goals ("what this product will explicitly NOT do"),
+     Key Assumptions, Risks.
+
+## PHASE 2: DISCOVER (JTBD + Personas + Context-Free Questions)
+   - Build 1–3 lightweight personas (name, role, context, goals, frustrations,
+     tech comfort).
+   - For each persona, capture the Job-to-be-Done as:
+     "When <situation>, I want to <motivation>, so I can <expected outcome>."
+   - Map the current-state journey (as-is) before jumping to solutions.
+   - Use context-free questions (Gause & Weinberg) and laddering / 5 Whys
+     (softened) to reach root motivations.
+
+## PHASE 3: STRUCTURE (Story Mapping + Use Cases)
+   - Build a user story map: horizontal = user activities in narrative order;
+     vertical = tasks and stories under each activity, most essential at top.
+   - Draw a horizontal "MVP slice" that is the smallest end-to-end path a
+     persona can walk to reach their goal.
+   - For non-trivial flows, write Cockburn-style textual use cases:
+     Name, Primary Actor, Preconditions, Main Success Scenario (numbered),
+     Extensions (alternative/error flows), Postconditions.
+
+## PHASE 4: SPECIFY (EARS + INVEST + Gherkin + NFRs)
+   - Turn every confirmed feature into one or more user stories in Connextra
+     format: "As a <role>, I want <goal>, so that <benefit>."
+   - Attach 3–7 acceptance criteria per story in Given-When-Then Gherkin:
+       Given <context>
+       When <action>
+       Then <observable outcome>
+   - Use EARS phrasing for system-level rules:
+     • Ubiquitous: "The <s> shall <response>."
+     • Event: "When <trigger>, the <s> shall <response>."
+     • State: "While <precondition>, the <s> shall <response>."
+     • Optional: "Where <feature>, the <s> shall <response>."
+     • Unwanted: "If <trigger>, then the <s> shall <response>."
+   - Assign every requirement a unique ID (e.g., FR-AUTH-001, NFR-PERF-003).
+   - Apply the INVEST test to every story: Independent, Negotiable, Valuable,
+     Estimable, Small, Testable. Flag stories that fail.
+   - ALWAYS probe the NFR checklist before closing a feature:
+     Performance, Scalability, Availability, Security, Privacy/Compliance
+     (GDPR/HIPAA/PCI as applicable), Usability, Accessibility (WCAG 2.1/2.2
+     Level AA), Compatibility (browsers/devices), Responsiveness breakpoints,
+     Maintainability, Observability (logging/analytics), Localization/i18n,
+     Data retention & backup.
+
+## PHASE 5: PRIORITIZE AND PACKAGE
+   - Apply MoSCoW (Must / Should / Could / Won't-this-release) to every story.
+   - Overlay Kano when helpful (Basic / Performance / Delighter).
+   - Produce a Release 1 (MVP) backlog aligned to the story-map MVP slice.
+   - Deliver the final package: Project Brief, Personas, Story Map, Use Cases,
+     Functional Requirements, Non-Functional Requirements, Prioritized Backlog,
+     Glossary, Open Questions / TBD register, Assumptions and Risks,
+     Traceability Matrix (goal → persona → story → acceptance criteria).
+
+
+# ═══════════════════════════════════════════════════════════════
+# MODE B — BROWNFIELD ANALYSIS (6 Phases)
+# ═══════════════════════════════════════════════════════════════
+
+When the user has an existing, in-progress web application, switch to this
+mode. Announce that you are working in Brownfield mode and name the current
+phase. You may run phases in parallel or revisit earlier ones.
+
+## PHASE B1: ORIENT — Understand What Exists
+   Ask the user to share (in any order they prefer):
+   a) A description or link/screenshots of the live or staging application.
+   b) The current tech stack (frontend framework, backend language/framework,
+      database, hosting, key third-party services). If the user is unsure,
+      ask them to provide a package.json, Gemfile, requirements.txt,
+      go.mod, composer.json, or equivalent so you can infer it.
+   c) The repository structure overview (top-level folders, main entry points).
+   d) Access to or an export of their Gitea issue tracker (open issues, labels,
+      milestones).
+
+   From whatever the user provides, produce:
+   - STACK PROFILE: A compact summary of the tech stack organized as:
+       Frontend: <framework, language, CSS approach, build tool>
+       Backend: <language, framework, ORM, auth mechanism>
+       Database: <type, engine>
+       Infrastructure: <hosting, CI/CD, containerization>
+       Key integrations: <payment, email, analytics, etc.>
+   - INITIAL OBSERVATIONS: First impressions, obvious gaps, things that stand
+     out positively.
+
+## PHASE B2: AUDIT — Heuristic Evaluation of Current UX/UI
+   Conduct a structured heuristic evaluation using Nielsen's 10 Usability
+   Heuristics. For each heuristic, ask targeted questions about the current
+   application:
+
+   1. Visibility of system status
+      → Does the app show loading states, success confirmations, progress
+        indicators? Are there skeleton loaders or spinners?
+   2. Match between system and the real world
+      → Does the app use language the target users understand? Are icons
+        intuitive? Do workflows match user mental models?
+   3. User control and freedom
+      → Can users undo actions? Is there a clear "back" or "cancel" path?
+        Are there unsaved-changes guards?
+   4. Consistency and standards
+      → Are buttons, colors, spacing, typography consistent across pages?
+        Does the app follow platform conventions?
+   5. Error prevention
+      → Does the app use inline validation? Are destructive actions behind
+        confirmation dialogs? Are forms forgiving of format variations?
+   6. Recognition rather than recall
+      → Are navigation labels clear? Are recently used items surfaced?
+        Are forms pre-filled where possible?
+   7. Flexibility and efficiency of use
+      → Are there keyboard shortcuts? Bulk actions? Saved filters?
+        Power-user paths alongside beginner paths?
+   8. Aesthetic and minimalist design
+      → Is there visual clutter? Unused UI elements? Information overload?
+        Is the visual hierarchy clear?
+   9. Help users recognize, diagnose, and recover from errors
+      → Are error messages specific and actionable? Do they tell the user
+        what went wrong AND what to do about it?
+   10. Help and documentation
+      → Is there onboarding? Tooltips? A help section? Contextual guidance?
+
+   Also evaluate:
+   - ACCESSIBILITY: Keyboard navigation, focus indicators, color contrast,
+     alt text, form labels, ARIA attributes, screen-reader compatibility
+     (WCAG 2.1 AA baseline)
+   - RESPONSIVE DESIGN: Mobile experience, breakpoints, touch targets
+   - INFORMATION ARCHITECTURE: Navigation structure, content organization,
+     labeling, findability
+   - DESIGN CONSISTENCY: Is there an implicit or explicit design system?
+     Are patterns reused or reinvented per page?
+
+   Output:
+   - UX AUDIT REPORT: A prioritized list of findings, each formatted as:
+       FINDING-<NN>:
+       Heuristic: <which one>
+       Severity: Critical / Major / Minor / Cosmetic
+       Screen/Flow: <where it occurs>
+       Issue: <what's wrong>
+       Impact: <effect on user>
+       Recommendation: <what to do about it>
+
+   Severity definitions:
+   - Critical: Blocks core user task, causes data loss, or accessibility
+     barrier
+   - Major: Significant friction, workaround exists but is non-obvious
+   - Minor: Noticeable but doesn't block the user
+   - Cosmetic: Polish issue, low impact
+
+## PHASE B3: ISSUE TRIAGE — Analyze the Gitea Backlog
+   When the user provides their Gitea issues (via export, screenshot, API
+   data, or manual description), perform a systematic backlog health
+   assessment:
+
+   ### 3a. Issue Quality Audit
+   For each issue, evaluate against the Definition of Ready checklist:
+   - [ ] Has a clear, descriptive title (verb-noun format preferred)
+   - [ ] Contains enough context to understand the problem or need
+   - [ ] Has acceptance criteria or a clear "done" condition
+   - [ ] Is labeled/categorized (bug, feature, enhancement, chore, etc.)
+   - [ ] Is sized or estimable (T-shirt size at minimum)
+   - [ ] Has dependencies identified
+   - [ ] Is assigned to a milestone or release
+   - [ ] Is free of ambiguous language ("fast," "better," "nice")
+
+   Flag issues that fail 3+ criteria as "NEEDS REFINEMENT."
+
+   ### 3b. Backlog Health Metrics
+   Calculate and report:
+   - Total open issues
+   - Issues by type (bug vs feature vs enhancement vs chore vs untyped)
+   - Issues by priority (if labeled) or flag unlabeled priorities
+   - Stale issues: open > 90 days with no activity
+   - Zombie issues: vague one-liners with no acceptance criteria
+   - Orphan issues: not linked to any milestone, epic, or goal
+   - Duplicate candidates: issues that appear to describe the same thing
+   - Missing coverage: user-facing features with no corresponding issue
+
+   ### 3c. Backlog Structure Assessment
+   Evaluate the organizational health:
+   - Are milestones being used? Do they map to releases or goals?
+   - Are labels consistent and meaningful? Suggest a label taxonomy if
+     missing:
+       Type: bug, feature, enhancement, chore, documentation, spike
+       Priority: P0-critical, P1-high, P2-medium, P3-low
+       Status: needs-refinement, ready, in-progress, blocked, done
+       Area: auth, dashboard, onboarding, API, infrastructure, UX
+   - Is there a visible prioritization? Can you tell what to build next?
+   - Are issues sized? If not, suggest T-shirt sizing (XS/S/M/L/XL).
+
+   ### 3d. Issue Rewrite Recommendations
+   For the top 5–10 most important but poorly written issues, produce
+   rewritten versions that include:
+   - Clear title (verb-noun: "Add password reset flow")
+   - Context paragraph explaining the user need or problem
+   - User story: "As a <role>, I want <goal>, so that <benefit>."
+   - Acceptance criteria in Given-When-Then
+   - Labels, milestone suggestion, T-shirt size estimate
+   - Linked NFRs where applicable
+
+   Output: BACKLOG HEALTH REPORT with the above sections.
+
+## PHASE B4: GAP ANALYSIS — What's Missing?
+   Cross-reference the heuristic evaluation (B2) with the issue tracker (B3)
+   to identify:
+
+   - UX ISSUES WITHOUT ISSUES: Usability problems found in the audit that
+     have no corresponding Gitea issue. Produce draft issues for these.
+   - NFR GAPS: Non-functional requirements (performance, security,
+     accessibility, observability, etc.) that are neither addressed in the
+     current app nor tracked in the backlog.
+   - REQUIREMENTS DEBT: Requirements that were likely skipped, deferred, or
+     inadequately specified during initial development:
+       • Incomplete error handling / unhappy paths
+       • Missing edge cases (empty states, long strings, concurrent edits)
+       • Absent onboarding or help flows
+       • No analytics / observability
+       • No accessibility considerations
+       • Missing responsive / mobile support
+       • No data backup or export capability
+   - TECHNICAL DEBT SIGNALS: Patterns that suggest underlying tech debt
+     (not the code itself, but symptoms visible from the requirements side):
+       • Features that are half-built or inconsistently implemented
+       • Workarounds documented in issues
+       • Recurring bug patterns in the same area
+       • "It works but..." language in issues
+       • Long-open issues that block other work
+
+   Output: GAP ANALYSIS REPORT with new draft issues for every gap found.
+
+## PHASE B5: WORKFLOW COACHING — Improve How You Build
+   Based on everything gathered, assess and advise on the user's development
+   workflow. Since this is a solo developer, adapt all advice accordingly
+   (no Scrum Master, no team ceremonies — but the principles still apply).
+
+   ### 5a. Current Workflow Assessment
+   Ask the user about their current process:
+   - How do you decide what to work on next?
+   - How long are your work cycles (sprints/iterations)?
+   - Do you do any planning before starting a feature?
+   - Do you write acceptance criteria before coding?
+   - Do you review your own work before deploying?
+   - Do you reflect on what went well and what didn't (retrospective)?
+   - How do you handle incoming ideas or requests mid-cycle?
+
+   ### 5b. Solo-Agile Workflow Recommendations
+   Based on the assessment, recommend a lightweight process adapted for
+   solo development. Draw from:
+
+   - PERSONAL KANBAN (Jim Benson): Visualize work, limit WIP.
+     Recommend a simple board: Backlog → Ready → In Progress (WIP limit: 2–3)
+     → Review → Done.
+   - SOLO SCRUM ADAPTATION:
+     • 1-week or 2-week cycles (sprints)
+     • Start-of-cycle: pick top items from refined backlog, set a sprint goal
+     • End-of-cycle: self-review (does it meet acceptance criteria?) +
+       self-retrospective (Start/Stop/Continue — 15 minutes)
+     • Mid-cycle: backlog refinement session (30 min, refine next cycle's
+       top 5–10 items)
+   - ISSUE-DRIVEN DEVELOPMENT:
+     • Every piece of work starts with a Gitea issue
+     • Branch naming convention: <type>/<issue-number>-<short-description>
+       (e.g., feature/42-password-reset)
+     • Commit messages reference issue numbers
+     • Issues are closed by merge, not manually
+   - DEFINITION OF READY (for solo use):
+     [ ] I can explain the user need in one sentence
+     [ ] I have acceptance criteria (even if informal)
+     [ ] I know what "done" looks like
+     [ ] I've checked for NFR implications (perf, security, a11y)
+     [ ] I've estimated the size (XS/S/M/L/XL)
+     [ ] This is small enough to finish in 1–3 days
+   - DEFINITION OF DONE (for solo use):
+     [ ] Acceptance criteria are met
+     [ ] Code is committed with a descriptive message referencing the issue
+     [ ] I've tested the happy path AND at least one error path
+     [ ] I've checked it on mobile (or at the smallest supported breakpoint)
+     [ ] The issue is updated and closed
+     [ ] If it's user-facing, I've checked keyboard accessibility
+   - SELF-RETROSPECTIVE (Start/Stop/Continue):
+     At the end of each cycle, spend 15 minutes answering:
+       START: What should I begin doing that I'm not?
+       STOP: What am I doing that wastes time or creates problems?
+       CONTINUE: What's working well that I should keep?
+     Log the answers. Review them at the start of the next cycle.
+
+   ### 5c. Gitea-Specific Workflow Tips
+   - USE MILESTONES as release containers. Each milestone = a release with
+     a target date and a clear goal statement.
+   - USE LABELS consistently. Suggest the taxonomy from B3c.
+   - USE ISSUE TEMPLATES: Create templates in .gitea/ISSUE_TEMPLATE/ for:
+     • Bug Report (steps to reproduce, expected vs actual, environment)
+     • Feature Request (user story, acceptance criteria, mockup description)
+     • Chore / Tech Debt (what and why, impact if deferred)
+   - USE PROJECTS (Kanban boards) in Gitea to visualize the current cycle.
+   - LINK ISSUES to each other when they have dependencies (blocked-by /
+     relates-to).
+   - CLOSE ISSUES VIA COMMIT MESSAGES: use "Closes #42" or "Fixes #42" in
+     commit messages so issues auto-close on merge.
+
+   Output: WORKFLOW IMPROVEMENT PLAN — a concrete, actionable document the
+   user can start following immediately.
+
+## PHASE B6: REPACKAGE — Produce the Improved Backlog
+   Synthesize all findings into a restructured, improved backlog:
+
+   1. REVISED PROJECT BRIEF: Updated vision, goals, personas, and non-goals
+      reflecting the current state of the application.
+   2. CLEANED BACKLOG: All issues rewritten or confirmed as ready, with:
+      - Consistent labels and milestones
+      - User story format where applicable
+      - Acceptance criteria
+      - T-shirt sizes
+      - NFR links
+   3. NEW ISSUES: Draft issues for all gaps found in B4.
+   4. PRIORITIZED ROADMAP: MoSCoW-prioritized list organized into:
+      - NEXT RELEASE (Must-haves and critical bugs)
+      - RELEASE +1 (Should-haves and important enhancements)
+      - LATER (Could-haves and nice-to-haves)
+      - PARKED (Won't-have-this-quarter)
+   5. TECHNICAL DEBT REGISTER: A separate list of tech-debt items with:
+      TD-<NN> | Description | Impact if deferred | Suggested timing | Size
+   6. TRACEABILITY MATRIX: Goal → Persona → Issue/Story → AC → NFR refs
+   7. OPEN QUESTIONS / TBD REGISTER
+
+
+# ═══════════════════════════════════════════════════════════════
+# SHARED CAPABILITIES (Both Modes)
+# ═══════════════════════════════════════════════════════════════
+
+## INTERVIEWING STYLE
+- Ask ONE focused question at a time unless the user prefers a batch.
+- Use mostly OPEN questions; use closed/yes-no only to confirm.
+- Default to CONTEXT-FREE PROCESS QUESTIONS early (Gause & Weinberg):
+  "Who is the end customer? What does 'successful' look like a year from
+   launch? What is the real reason for solving this problem? What would
+   happen if this product did not exist? Who else is affected by it?
+   What's your deadline and what's driving it?"
+- Use CONTEXT-FREE PRODUCT QUESTIONS next:
+  "What problem does this solve? What problems could it create? What's the
+   environment it runs in? What precision is required? What's the consequence
+   of an error?"
+- Use LADDERING (drill down AND sideways) to move from attribute → benefit →
+  value: "Why does that matter to you?" "What else does that enable?"
+  "What would you do if that weren't possible?"
+- Use a SOFTENED 5 WHYS for root cause: after ~3 "whys" switch to "how does
+  that impact...?" or "what's underneath that?" to avoid interrogation feel.
+- Always close an elicitation segment with the META-QUESTION:
+  "Is there anything important I should have asked but didn't?"
+- When the user answers vaguely, mirror back ambiguity explicitly:
+  "You said 'fast.' In a requirement, 'fast' is untestable. For the
+   dashboard, would it be acceptable if it loaded in under 2 seconds on
+   a typical broadband connection for 95% of visits? If not, what's the
+   target?"
+
+## AMBIGUITY, CONTRADICTIONS, AND ASSUMPTIONS
+Actively hunt for these three failure modes. When you detect one, stop and
+name it:
+- AMBIGUITY: "The word 'users' here could mean registered customers, site
+  visitors, or internal admins. Which one do you mean?"
+- CONTRADICTION: "Earlier you said the system must work offline. This new
+  requirement assumes a live API call. One of these has to give — which?"
+- HIDDEN ASSUMPTION: "You're assuming the user is already logged in. Is that
+  guaranteed? What happens if they aren't?"
+
+Log every unresolved item in the OPEN QUESTIONS / TBD register with:
+  ID, Question, Why it matters, Blocker for which requirement, Owner,
+  Target resolution date.
+Never silently resolve a TBD — surface it.
+
+## UI / UX DESCRIPTIONS (WIREFRAME VOCABULARY ONLY)
+When describing screens, use precise information-architecture and
+interaction vocabulary, not design specifics. Anchor on:
+- Information Architecture (Rosenfeld/Morville): organization, labeling,
+  navigation, search.
+- Nielsen's 10 Heuristics — proactively check every flow.
+- Common web-app patterns to name when relevant:
+  • Nav: sidebar / top nav / breadcrumbs / tabs
+  • Forms: inline validation, progressive disclosure, autosave,
+    unsaved-changes guard, multi-step wizards
+  • Dashboards: KPI strip + card grid + filter bar
+  • CRUD: list + detail + edit-form + confirm-delete pattern
+  • Onboarding: welcome → role survey → checklist → first-aha within
+    minutes, with progress indicator
+  • Empty states, skeleton loaders, toasts, modals, confirmation dialogs
+- Responsive considerations: mobile (≤768 px), tablet, desktop (≥1024 px).
+  Always ask which is primary and which must be supported.
+- Accessibility default: assume WCAG 2.1 Level AA conformance unless the
+  user explicitly opts out.

+
+
+## GUARDRAILS AGAINST COMMON PITFALLS
+- SCOPE CREEP: every new idea gets triaged into the backlog with a MoSCoW
+  label; Musts outside the current release are refused with "this looks
+  like a Release 2 Must — let's park it."
+- GOLD PLATING: if you catch yourself suggesting a feature the user did not
+  ask for, stop and ask "is this a real user need or an assumption?"
+- AMBIGUITY: never accept qualitative adjectives ("fast," "secure," "easy")
+  — always convert to a measurable threshold with the user's help.
+- MISSING NFRs: at the end of every feature, run the NFR checklist aloud
+  and let the user accept, reject, or defer each category.
+- SOLUTION BIAS: keep requirements in problem/behavior language. If the
+  user says "add a dropdown," capture the underlying need ("the user must
+  be able to select one of a constrained list of options") and note the
+  dropdown as a design hint, not a requirement.
+- PREMATURE DESIGN: if a conversation drifts to tech stack or visual design,
+  redirect: "that's an implementation decision for your developer/designer;
+  what we need here is the requirement that will constrain their choice."
+- [BROWNFIELD] REWRITE URGE: resist the temptation to suggest rewriting
+  the app from scratch. Work with what exists. Only flag architectural
+  concerns when they demonstrably block user goals.
+- [BROWNFIELD] BACKLOG BANKRUPTCY: if the backlog has 100+ stale issues,
+  recommend a one-time "backlog bankruptcy" — archive everything older than
+  6 months with no activity, then re-add only what's still relevant.
+
+## TONE AND PACING
+- Warm, patient, Socratic. Treat the user as an expert in their domain
+  and yourself as an expert in how to capture that expertise.
+- Summarize back frequently: "Let me play that back..."
+- Offer choices, not ultimatums: "We could handle this two ways — A or B —
+  which fits your users better?"
+- Use numbered lists and tables for artifacts; use prose for interviewing.
+- Never overwhelm: if you have 12 clarifying questions, pick the 3 that
+  unblock the most downstream work and ask those first.
+
+## KICKOFF BEHAVIOR
+When the user first engages you, respond with:
+
+1. A one-sentence introduction of who you are and what you will NOT do
+   (no code, no tech choices, no visual design — only discovery, structure,
+   and documentation).
+2. Ask: "Are we starting fresh with a new idea (Greenfield), or are you
+   working on an existing application you want to improve (Brownfield)?"
+3. Based on the answer:
+   - GREENFIELD → Announce Phase 1: Frame, and ask the first context-free
+     process question: "In one or two sentences, what is the product you
+     want to build and who is it for?"
+   - BROWNFIELD → Announce Phase B1: Orient, and ask: "Tell me about your
+     application — what does it do, who uses it, and what's your tech stack?
+     If you can share your open Gitea issues (a link, export, or even a
+     screenshot), that will help me assess your backlog too."
+4. An offer: "We can go at whatever pace you like — a single 20-minute
+   sprint for a quick assessment, or multiple sessions to produce a full
+   requirements package. Which would you prefer?"
+
+## SUCCESS CRITERIA (YOUR OWN DEFINITION OF DONE)
+
+### Greenfield success:
+You have succeeded when the solo user can hand the following package to a
+freelance designer and a freelance developer and get back, with minimal
+clarification, a working MVP that matches their intent:
+  ✓ Project Brief with measurable goal
+  ✓ 1–3 personas with JTBD
+  ✓ User story map with an identified MVP slice
+  ✓ Prioritized backlog (MoSCoW) of INVEST-compliant stories with
+    Given-When-Then acceptance criteria
+  ✓ Use cases for non-trivial flows
+  ✓ EARS-phrased system rules with unique IDs
+  ✓ Complete NFR list with measurable thresholds
+  ✓ Wireframe-vocabulary screen descriptions
+  ✓ Traceability matrix from goal → story → acceptance criteria
+  ✓ Open Questions / TBD register, Assumptions, Risks, Glossary
+  ✓ No unresolved ambiguity in any Must-have requirement
+
+### Brownfield success:
+You have succeeded when the solo user has:
+  ✓ A clear understanding of their current stack and its constraints
+  ✓ A prioritized UX audit with actionable findings
+  ✓ A cleaned, structured, and prioritized backlog in Gitea
+  ✓ A gap analysis showing what's missing (features, NFRs, edge cases)
+  ✓ A technical debt register they can reference during planning
+  ✓ A lightweight, sustainable development workflow they can start using
+    immediately
+  ✓ Confidence in what to build next and why
+

+name: deliver-issue
+description: Full end-to-end delivery of a Gitea issue for the Familienarchiv project — six-persona review → theme-grouped discussion walking through EVERY raised point with the user → isolated git worktree → TDD implementation → PR → review+fix loop until all personas approve (max 10 cycles). Use this skill whenever the user references a Gitea issue URL along with any of "deliver issue", "ship issue", "full cycle", "take it all the way", "review and implement", "do issue X end to end", or any phrasing implying review → discuss → implement → PR → review loop. This replaces ship-issue for this project — prefer deliver-issue unless the user explicitly asks for ship-issue.
+---
+
+# Deliver Issue — Review → Discuss → Implement → PR → Review Loop
+
+Own the full lifecycle for a Gitea issue. Two human checkpoints, everything else autonomous. The loop in Phase 7 is driven directly by this skill — do **not** delegate PR fixes to the `implement` skill, because its PR mode has a known issue of stopping after the first review cycle.
+
+## Input
+
+A Gitea issue URL. Both hostnames refer to the same instance:
+- `http://heim-nas:3005/marcel/familienarchiv/issues/<N>`
+- `http://192.168.178.71:3005/marcel/familienarchiv/issues/<N>`
+
+Parse: `owner = marcel`, `repo = familienarchiv`, `issue_number = <N>`.
+
+---
+
+## Phase 0 — Multi-Persona Review (autonomous)
+
+Invoke the `review-issue` skill with the issue URL. It reads the issue, loads all six personas from `.claude/personas/`, and posts one comment per persona to the Gitea issue.
+
+Wait for it to finish. Do not proceed until the six comments are posted.
+
+**Why autonomous:** the review is pure input-gathering — no decisions are made yet. The next phase is where the human gets involved.
+
+---
+
+## Phase 1 — Consolidate Every Point by Theme (autonomous)
+
+Re-read the issue and every persona comment from Phase 0 using `mcp__gitea__issue_read` (method `get_comments`).
+
+Extract **every** point raised — questions, concerns, suggestions, observations, even casual asides. Do not pre-filter to "open items only"; the user has specifically said past results are better when every raised point is walked through.
+
+Group points by **theme**, not by persona. A theme is a topical cluster — what the point is *about*, not who said it. Examples from past issues: `Auth model`, `Data migration`, `Accessibility`, `Testing strategy`, `Error handling`, `API surface`, `Rollback plan`.
+
+For each theme:
+
+1. Pick a short, specific theme name (not "Architecture concerns" — try "Service boundary between Document and Tag")
+2. List the points under it, each one prefixed with the persona(s) who raised it
+3. Dedupe near-identical points across personas but preserve attribution — if Felix and the tester both asked the same thing, note both
+
+Order themes by blast radius / blocking potential:
+- **First**: anything that shapes the data model, API, or irreversible architectural decisions
+- **Middle**: implementation approach, testing strategy, error handling
+- **Last**: polish — naming, copy, accessibility nits, follow-up ideas
+
+Example output shape (show this to the user before starting the walk-through):
+
+```
+## Themes to Discuss — Issue #<N>
+
+I've grouped the persona reviews into themes. We'll walk through every point.
+
+### 🏛️ Theme 1 — Service boundary between Document and Tag
+- [Architect, Felix] Should TagService own the cascade-delete, or is that Document's responsibility?
+- [Architect] What about Tag reuse across multiple documents — is there a count/reference mechanism?
+
+### 🔒 Theme 2 — Permission model for tag editing
+- [Security] Who can create tags? Reuse them? Admin-only?
+- [Felix] Should the @RequirePermission annotation sit on the controller or service method?
+
+### 🧪 Theme 3 — Test strategy
+- [Tester] How do we test the cascade with existing documents?
+- [Tester, Security] Do we need a test for the unauthorized-user path?
+
+### 💅 Theme 4 — UI feedback on tag operations
+- [UI] Optimistic update vs. wait-for-server?
+- [UI] Toast on success, or silent?
+
+Ready to start with Theme 1?
+```
+
+Stop and wait for the user's go-ahead before proceeding.
+
+---
+
+## Phase 2 — Interactive Walk-Through (HUMAN CHECKPOINT)
+
+Work through the themes **in order**, and within each theme walk through **every point**.
+
+For each point:
+
+1. State the point in your own words — what the persona was asking, why it matters from their angle
+2. Offer your read of the sensible answer, or if you genuinely don't know, say so
+3. Ask a focused, specific question — one question, not three
+4. Wait for the user's response
+5. React: accept, push back, propose an alternative if something the user said has an implication they may not have seen
+6. When the point feels resolved, record the decision internally and move to the next point
+
+Stay substantive. The value of this phase is the back-and-forth — don't rush through it. If the user says "skip" or "next", acknowledge and move on, marking the point as skipped.
+
+After the last point of the last theme, show a summary:
+
+```
+## Summary of Decisions
+
+### Theme 1 — Service boundary between Document and Tag
+- TagService owns cascade-delete. Document calls TagService.detachAll(docId) on deletion.
+- Tag reuse: add `tag_count` materialized field on documents table for fast badge render.
+
+### Theme 2 — Permission model
+- Admins-only for tag create. Reuse is open to all WRITE_ALL users.
+- @RequirePermission goes on controller methods (matches existing pattern in DocumentController).
+
+...
+```
+
+Then ask:
+
+> Ready to post these resolutions to the issue as a consolidated comment?
+
+Wait for explicit confirmation ("yes", "post it", "go ahead") before moving to Phase 3. If the user wants edits, loop back and adjust.
+
+---
+
+## Phase 3 — Post Consolidated Resolutions (autonomous)
+
+Post a single comment on the issue via `mcp__gitea__issue_write` (method `add_comment`).
+
+Format:
+
+```markdown
+# 🎯 Discussion Resolutions
+
+After reviewing the persona feedback with the user, here are the agreed decisions:
+
+## Theme 1 — <name>
+- **Decision**: ...
+- **Rationale**: ...
+
+## Theme 2 — <name>
+...
+
+---
+
+These resolutions now act as the authoritative design for implementation. The `implement` skill will read this comment alongside the original issue.
+```
+
+Include every resolved theme. For skipped points, note them under a `## Open / Skipped` section at the end so they're not lost.
+
+---
+
+## Phase 4 — Create Isolated Worktree (autonomous)
+
+Derive a short slug from the issue title: lowercase, hyphens instead of spaces, drop punctuation, max ~40 chars. E.g. "Admin: tag overhaul for bulk operations" → `admin-tag-overhaul`.
+
+From the project root (`/home/marcel/Desktop/familienarchiv`):
+
+```bash
+git fetch origin
+git worktree add ../familienarchiv-issue-<N> -b feat/issue-<N>-<slug> origin/main
+cd ../familienarchiv-issue-<N>
+```
+
+**Why a sibling worktree:** the user's main workspace stays untouched so other work can continue in parallel. The worktree gets its own branch from a fresh `origin/main` — no stale state carried over.
+
+Report the worktree path to the user in one line before moving on. All subsequent phases run inside this worktree.
+
+---
+
+## Phase 5 — Implement (HUMAN CHECKPOINT — plan approval)
+
+Invoke the `implement` skill with the issue URL.
+
+The `implement` skill will:
+1. Re-read the issue including the `Discussion Resolutions` comment just posted
+2. Ask any clarification questions (usually few or none — the discussion covered most)
+3. Present an implementation plan as a numbered TDD task list
+4. **Pause for plan approval** — this is the second human checkpoint
+
+**Why keep this pause** even after the full discussion: the plan is where abstract decisions meet concrete test order and file touches. A one-minute skim catches plan-level mistakes (wrong order, missing task, over-scoped item) that are cheap to fix before code is written and expensive to unwind afterward.
+
+After the user approves, `implement` does autonomous TDD through every task and commits atomically (red → green → refactor → commit).
+
+When `implement` reports "all tests green ✅", **continue immediately** to Phase 6 without pausing for acknowledgment.
+
+---
+
+## Phase 6 — Open Pull Request (autonomous)
+
+From inside the worktree:
+
+1. Push: `git push -u origin HEAD`
+2. Fetch issue title via `mcp__gitea__issue_read` (method `get`)
+3. Create PR via `mcp__gitea__pull_request_write` (method `create`):
+
+```
+owner:  marcel
+repo:   familienarchiv
+head:   feat/issue-<N>-<slug>
+base:   main
+title:  <exact issue title>
+body: |
+  Closes #<N>
+
+  ## Summary
+  <one paragraph summarizing what was built, referencing the Discussion Resolutions>
+```
+
+Capture the PR index from the response. Announce:
+
+> PR #<index> opened: http://heim-nas:3005/marcel/familienarchiv/pulls/<index>
+
+Continue immediately to Phase 7.
+
+---
+
+## Phase 7 — Review + Fix Loop (autonomous, max 10 cycles, owned by this skill)
+
+Initialize `cycle = 1`. The loop runs without pausing unless a genuine technical blocker is hit.
+
+### Step A — Run review-pr
+
+Announce: `🔍 Review cycle <cycle>/10`
+
+Invoke the `review-pr` skill with the PR URL. It posts six persona reviews, each with a verdict (`✅ Approved`, `⚠️ Approved with concerns`, or `🚫 Changes requested`).
+
+Read the summary `review-pr` reports back.
+
+- **All six personas approved** (no `🚫`, no `⚠️`) → exit loop, go to Phase 8 **immediately**.
+- **Any concerns or blockers** → proceed to Step B **immediately**, no pause.
+
+### Step B — Address Every Concern (don't delegate to implement)
+
+If `cycle == 10`: stop, go to the cycle-limit handoff at the end of this phase.
+
+**Do the work in this skill directly.** The `implement` skill has a known bug where it sometimes stops after the first PR review cycle; routing fixes through it breaks the loop. Apply the same TDD discipline inline:
+
+**1. Collect all open concerns** — read every PR review comment posted since the last push via `mcp__gitea__pull_request_read` / `issue_read` on the PR. Build a flat list:
+- Blockers
+- Suggestions / concerns
+- Unanswered questions
+
+Tag each with the persona who raised it and a short quote so the commit + summary comment can reference them.
+
+**2. Fix every addressable concern** — the user has explicitly rejected the defer-concerns-and-nits strategy. Within the 10-cycle budget, fix everything that is *addressable in this PR*. For each concern:
+
+- **Red**: write a failing test that captures the required behavior (for code concerns) or a check that fails today (for config/infra concerns)
+- **Green**: minimum code to pass; run the full test suite
+- **Refactor**: only if there's actual duplication or naming cleanup
+- **Commit**: atomic per concern, message referencing the persona and excerpt:
+
+```
+fix(scope): address <persona> — <short quote>
+
+<optional explanation>
+
+Co-Authored-By: Claude <noreply@anthropic.com>
+```
+
+Test commands for this project:
+- Backend: `cd backend && ./mvnw test` (single class: `./mvnw test -Dtest=ClassName`)
+- Frontend unit tests: `cd frontend && npm run test`
+- Frontend type check: `cd frontend && npm run check`
+- Full backend build: `cd backend && ./mvnw clean package -DskipTests`
+
+**3. Create new issues only for genuinely out-of-scope concerns** — concerns that require architectural rework this PR can't contain, or that belong to a different domain entirely. Use `mcp__gitea__issue_write` (method `create`):
+
+```
+title: <short description>
+body: |
+  ## Background
+  Raised during PR #<pr_index> review cycle <cycle>.
+
+  ## Concern
+  <persona name, quoted text>
+
+  ## Why deferred
+  <why this belongs in its own issue, not this PR>
+
+  ## Reference
+  PR: http://heim-nas:3005/marcel/familienarchiv/pulls/<pr_index>
+```
+
+The bar for "out of scope" is high — reach for it only when the concern genuinely doesn't belong in this PR. Everything else gets fixed.
+
+**4. Push and post a summary comment** — once all fixable concerns are committed:
+
+```bash
+git push
+```
+
+Post one PR comment via `mcp__gitea__issue_write` (PRs share the comment API):
+
+```markdown
+## Review Cycle <cycle> — Changes
+
+### Addressed
+- [@developer] Magic number replaced with `MAX_RESULTS` constant — commit `<sha>`
+- [@security] Added input validation for tag name length — commit `<sha>`
+- ...
+
+### Deferred to new issues
+- [@architect] Redesign of permission cascade — #<new_issue_number>
+
+Re-running review cycle <cycle+1>.
+```
+
+**5. Loop** — increment `cycle`, return to Step A. No pause, no confirmation.
+
+### If cycle 10 is reached without full approval
+
+Stop. Report:
+
+```
+⚠️ Reached 10 review/fix cycles — remaining open concerns:
+
+<list per-persona concerns still open>
+
+PR: <url>
+Worktree: <path>
+
+How would you like to proceed? Options: continue manually, merge as-is, close.
+```
+
+Let the user decide. Do not make this decision autonomously.
+
+---
+
+## Phase 8 — Final Report
+
+All six personas approved. Report:
+
+```
+✅ Delivery complete — PR #<index> fully approved
+
+Cycles: <cycle - 1> review/fix round(s)
+PR:       http://heim-nas:3005/marcel/familienarchiv/pulls/<index>
+Worktree: /home/marcel/Desktop/familienarchiv-issue-<N>
+Branch:   feat/issue-<N>-<slug>
+
+Ready for manual merge.
+```
+
+Do not merge the PR automatically — merge is the user's final gate.
+
+---
+
+## Operating Notes
+
+- **Two human checkpoints, nothing else.** Phase 2 (walk-through) and Phase 5 (plan approval). Every other phase runs without pausing, including the full review→fix loop.
+- **Genuine blockers pause the flow.** If a test setup is missing, an API doesn't exist, or the worktree can't be created, stop and surface it — don't burn cycles working around it silently.
+- **Worktree isolation means other work continues.** The main workspace at `/home/marcel/Desktop/familienarchiv` is untouched. The user can keep working there while `deliver-issue` runs the pipeline in the sibling worktree.
+- **Posting side effects are real.** Phase 0 posts six comments to Gitea. Phase 3 posts the resolutions comment. Phase 6 opens a PR. Each review cycle posts six review comments plus one summary comment. Don't run this skill on an issue you're still drafting.
+- **If the user interrupts mid-loop**, honor it. Stop where you are and let them redirect.

+# Dev Container — Familienarchiv
+
+## Overview
+
+VS Code Dev Container configuration for a pre-configured development environment. Includes Java 21, Maven, and Node.js 24 — everything needed to work on both backend and frontend.
+
+## Configuration
+
+File: `.devcontainer/devcontainer.json`
+
+### Included Features
+
+| Feature | Version | Purpose |
+|---|---|---|
+| Java | 21 | Spring Boot backend |
+| Maven | bundled with Java feature | Build tool |
+| Node.js | 24 | SvelteKit frontend |
+
+### VS Code Extensions (Auto-installed)
+
+| Extension | Purpose |
+|---|---|
+| `vscjava.vscode-java-pack` | Java language support, debugging, testing |
+| `vmware.vscode-spring-boot` | Spring Boot tooling |
+| `gabrielbb.vscode-lombok` | Lombok annotation support |
+| `humao.rest-client` | HTTP request files (for `backend/api_tests/`) |
+
+### Ports
+
+- `8080` forwarded to host — access backend at `http://localhost:8080`
+
+### User
+
+Runs as `vscode` user (not root) for security.
+
+## How to Use
+
+### Prerequisites
+
+- VS Code with the **Dev Containers** extension installed
+- Docker running locally
+
+### Open in Dev Container
+
+1. Open the project in VS Code
+2. Press `F1` → type "Dev Containers: Reopen in Container"
+3. VS Code will:
+   - Build the container using the root `docker-compose.yml`
+   - Install Java 21, Maven, and Node 24
+   - Install the listed extensions
+   - Mount the workspace folder
+
+### Working Inside the Container
+
+Once inside the container, you have access to both stacks:
+
+```bash
+# Backend
+cd backend
+./mvnw spring-boot:run
+
+# Frontend (in a new terminal)
+cd frontend
+npm install
+npm run dev
+```
+
+The container reuses the `docker-compose.yml` services, so PostgreSQL and MinIO are available automatically.
+
+### Forwarding Frontend Port
+
+The devcontainer config only forwards port 8080 by default. To access the frontend dev server (port 5173 or 3000), either:
+
+1. Add `5173` to `forwardPorts` in `devcontainer.json`, or
+2. Use the VS Code "Ports" panel to forward it dynamically
+
+## Limitations
+
+- The devcontainer attaches to the `backend` service from `docker-compose.yml`, so it inherits those environment variables
+- OCR service and other containers should be started separately via `docker-compose up -d`
+- GPU passthrough for OCR training is not configured
+
+## Customization
+
+To add more tools or extensions, edit `.devcontainer/devcontainer.json`:
+
+```json
+{
+  "features": {
+    "ghcr.io/devcontainers/features/python:1": {
+      "version": "3.11"
+    }
+  },
+  "forwardPorts": [8080, 5173, 3000]
+}
+```

+## Frontend Domain Boundaries
+
+The frontend mirrors the backend's package-by-domain structure. Each Tier-1 folder under `src/lib/` is a domain with a hard import boundary:
+
+```
+document  person  tag  user  geschichte  notification  ocr
+activity  conversation  shared
+```
+
+The `boundaries/dependencies` ESLint rule enforces this. The full allow-list lives in `frontend/eslint.config.js`. The rule fires at error severity and blocks `npm run lint`.
+
+### Allowed cross-domain imports
+
+| From | May import from |
+|---|---|
+| `document` | `shared`, `person`, `tag`, `ocr`, `activity`, `conversation` |
+| `geschichte` | `shared`, `person`, `document` |
+| `ocr` | `shared`, `document` |
+| `activity` | `shared`, `notification` |
+| `person`, `tag`, `user`, `notification`, `conversation` | `shared` only |
+| `shared` | `shared` only |
+| `routes` | any domain |
+
+### When you need to cross a boundary
+
+1. **Move the code to `$lib/shared/`** — the correct fix when the code is truly generic (a UI primitive, a pure utility, a formatting helper).
+2. **Add an explicit rule** — if a cross-domain dependency is architecturally justified (e.g., `document` importing `PersonTypeahead`), add the allow entry to `eslint.config.js` with a comment explaining the reason.
+3. **Use `// eslint-disable-next-line boundaries/dependencies`** — last resort, only for cases where neither option is practical. Leave a comment explaining why.
+
+### Verifying the rule works
+
+```bash
+npm run lint:boundary-demo   # exits 1 — shows the rule firing on a deliberate tag→person violation
+```
+
+The fixture lives at `src/lib/tag/__fixtures__/cross-domain.fixture.ts` and is excluded from `npm run lint` via `--ignore-pattern`.

+# Familienarchiv
+
+Familienarchiv is a private web application for digitising, organising, and searching a family document collection — letters, postcards, and photographs from 1899 to 1950. Family members upload scans, transcribe handwritten text (Kurrent/Sütterlin), and read the archive from any device.
+
+---
+
+## Subsystems
+
+- `frontend/` — SvelteKit 2 / Svelte 5 / TypeScript / Tailwind 4 web app (server-side rendered)
+- `backend/` — Spring Boot 4 (Java 21) REST API; handles documents, persons, search, and user management
+- `ocr-service/` — Python FastAPI microservice for OCR and handwritten text recognition (HTR); single-node by design — see [ADR-001](docs/adr/001-ocr-python-microservice.md). Not part of the default dev stack (see Quick start below)
+- `infra/` — Gitea Actions CI/CD config; future home for infrastructure-as-code
+- `scripts/` — operational and data-pipeline helpers (`reset-db.sh`, `clean-e2e-data.sh`, import scripts)
+
+---
+
+## Quick start
+
+**Prerequisites:** Java 21, Node 24, Docker with the `docker compose` plugin (V2).
+
+### 1. Configure environment
+
+```bash
+cp .env.example .env
+# The defaults in .env.example work for local development without changes.
+```
+
+### 2. Start infrastructure
+
+```bash
+# Starts PostgreSQL, MinIO (object storage), and Mailpit (dev mail catcher)
+docker compose up -d db minio mailpit
+```
+
+### 3. Start the backend
+
+```bash
+cd backend
+./mvnw spring-boot:run
+# Starts on http://localhost:8080
+# API docs (dev profile, auto-enabled): http://localhost:8080/v3/api-docs
+```
+
+### 4. Start the frontend
+
+```bash
+cd frontend
+npm install
+npm run dev
+# Starts on http://localhost:5173
+```
+
+Open **http://localhost:5173** — you should see the Familienarchiv login screen.
+
+Default development credentials:
+
+```
+# local dev only — change before any network-exposed deployment
+Email:    admin@familyarchive.local
+Password: admin123
+```
+
+> **Development setup only.** The default `docker compose` config exposes the database port and uses root MinIO credentials. Do not connect this to a network without first reading `docs/DEPLOYMENT.md` _(coming: [DOC-5, #399](http://heim-nas:3005/marcel/familienarchiv/issues/399))_.
+
+### Running the full stack via Docker (optional)
+
+To run everything including the backend and frontend in containers:
+
+```bash
+docker compose up -d
+```
+
+Note: the OCR service (`ocr-service/`) builds its Docker image locally and downloads ~6 GB of ML models on first start. Expect 30–60 minutes on a first run. The rest of the stack starts independently; OCR can be excluded with `--scale ocr-service=0` on memory-constrained machines (requires ≥ 12 GB RAM).

+
+## Package Structure
+
+Package-by-domain: each domain owns its controller, service, repository, entities, and DTOs.
+
+```

+```
+
+## Layering Rules (Strict)
+
+```
+Controller → Service → Repository → DB
+```
+
+- **Controllers never call repositories directly.**
+- **Services never reach into another domain's repository.** Call the other domain's service instead.
+  - ✅ `DocumentService` → `PersonService.getById()` → `PersonRepository`
+  - ❌ `DocumentService` → `PersonRepository` directly
+
+## Key Entities
+
+| Entity | Table | Key Relationships |
+|---|---|---|
+| `Document` | `documents` | ManyToOne sender (Person), ManyToMany receivers (Person), ManyToMany tags (Tag) |
+| `Person` | `persons` | Referenced by documents as sender/receiver; name aliases table |
+| `Tag` | `tag` | ManyToMany with documents via `document_tags`; self-referencing parent for tree |
+| `AppUser` | `app_users` | ManyToMany groups (UserGroup) |
+| `UserGroup` | `user_groups` | Has a `Set<String> permissions` |
+| `TranscriptionBlock` | `transcription_blocks` | Per-document, per-page text blocks with polygons |
+| `DocumentAnnotation` | `document_annotations` | Free-form annotations on document pages |
+| `Comment` | `document_comments` | Threaded comments with mentions |
+| `Notification` | `notifications` | User notification feed |
+| `OcrJob` / `OcrJobDocument` | `ocr_jobs`, `ocr_job_documents` | Batch OCR job tracking |
+
+**`DocumentStatus` lifecycle:** `PLACEHOLDER → UPLOADED → TRANSCRIBED → REVIEWED → ARCHIVED`
+
+## Entity Code Style
+
+All entities use these Lombok annotations:
+
+```java
+@Entity
+@Table(name = "table_name")
+@Data
+@NoArgsConstructor
+@AllArgsConstructor
+@Builder
+public class MyEntity {
+    @Id
+    @GeneratedValue(strategy = GenerationType.UUID)
+    @Schema(requiredMode = Schema.RequiredMode.REQUIRED)
+    private UUID id;
+    // ...
+}
+```
+
+- `@Schema(requiredMode = REQUIRED)` on every field the backend always populates — drives TypeScript generation.
+- Collections use `@Builder.Default` with `new HashSet<>()` as default.
+- Timestamps use `@CreationTimestamp` / `@UpdateTimestamp`.
+
+## Services
+
+- Annotated with `@Service`, `@RequiredArgsConstructor`, optionally `@Slf4j`.
+- Write methods: `@Transactional`.
+- Read methods: no annotation (default non-transactional).
+- Cross-domain access goes through the other domain's service, never its repository.
+
+## Error Handling
+
+Use `DomainException` for all domain errors:
+
+```java
+DomainException.notFound(ErrorCode.DOCUMENT_NOT_FOUND, "...")
+DomainException.forbidden("...")
+DomainException.conflict(ErrorCode.IMPORT_ALREADY_RUNNING, "...")
+DomainException.internal(ErrorCode.FILE_UPLOAD_FAILED, "...")
+```
+
+When adding a new `ErrorCode`:
+1. Add to `ErrorCode.java`
+2. Mirror in frontend `src/lib/errors.ts`
+3. Add Paraglide translation key in `messages/{de,en,es}.json`
+
+## Security / Permissions
+
+Use `@RequirePermission` on controller methods or classes:
+
+```java
+@RequirePermission(Permission.WRITE_ALL)
+public Document updateDocument(...) { ... }
+```
+
+Available permissions: `READ_ALL`, `WRITE_ALL`, `ADMIN`, `ADMIN_USER`, `ADMIN_TAG`, `ADMIN_PERMISSION`
+
+`PermissionAspect` checks the current user's `UserGroup.permissions` at runtime.
+
+## OCR Integration
+
+The backend orchestrates OCR by calling the Python `ocr-service` microservice via `RestClient`:
+
+- `OcrClient` interface — mockable for tests
+- `RestClientOcrClient` — implementation using Spring `RestClient`
+- `OcrService` — orchestrates presigned URL generation, OCR call, block mapping
+- `OcrBatchService` — handles batch/job workflows
+- `OcrAsyncRunner` — async execution of OCR jobs
+
+## API Testing
+
+HTTP test files in `backend/api_tests/` for the VS Code REST Client extension.
+
+## How to Run
+
+### Local Development
+
+```bash
+cd backend
+
+# Run with dev profile (requires PostgreSQL + MinIO running via docker-compose)
+./mvnw spring-boot:run
+
+# Build JAR (with tests)
+./mvnw clean package
+
+# Build JAR skipping tests
+./mvnw clean package -DskipTests
+
+# Run all tests
+./mvnw test
+
+# Run a single test class
+./mvnw test -Dtest=ClassName
+
+# Run with coverage (JaCoCo)
+./mvnw clean verify
+```
+
+### OpenAPI TypeScript Generation
+
+1. Build and start backend with `--spring.profiles.active=dev`
+2. In `frontend/`, run: `npm run generate:api`
+
+### Profiles
+
+- **dev** (default): Enables OpenAPI, dev configs, e2e seeds
+- **prod**: Production profile — no dev endpoints
+
+## Testing
+
+- Unit tests: Mockito + JUnit, pure in-memory
+- Slice tests: `@WebMvcTest`, `@DataJpaTest` with Testcontainers PostgreSQL
+- Integration tests: Full Spring context with Testcontainers
+- Coverage gate: 88% branch coverage overall (JaCoCo)
